To all whom it may concern Be it knownthat 1, WILLIAM J. KENELY, acitizen'of the United States, residing at Elizabeth, in the'county ofUnion and State of New Jersey, have invented certain Improvements inHeating-Flues, of which the following is a specification.

This invention relates to heating-fines for chimneys of dwelling housesand the like, and the objects of the invention are to provide a fluebranching from the chimney off through a room and back again to thechimney, by which the heat of the escaping gases may be utilized to warmsaid room; to provide branch flue sections or boxes which can beincorporated in a chimney during its which sections or boxes the saidfines can be supplied at any subsequent time; to provide for a pluralityof fines atthe same floor or level; to provide suitable dampers or"valves whereby the gases may be directed as "desired and the draft ofthe fire preserved; to secure simplicity of constructionandinstallation, and to obtain other advantages and results as may bebrought out inthe following description. l

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts throughout the several views, Figure 1is an elevation, partly in section, of mydevice as applied to a chimney,and Fig.

2 is a perspective view of a portion of a room illustrating that portionof the chitinney to which the heating flue is applied.

In the specific embodiment of the invention illustrated in saiddrawings, 1 indicates the wall into which the chimney 2' is built ascustomary, the said chimney being shown as rectangular in cross section.It is to be understood, however, that the invention is equallyapplicable to chimneys of other cross sections and that I do not wish tolimit the scope of my patent to any particular design of chimney.Preferably near the floor is in-. corporated into the chimney aheat-flue sec tion 3, the same being preferably composed of somematerial which is readily molded into the desired shape, as cement. Saidsection 3 is hollow and conforms substantially to the chimney, so as toform a longitudinal portion thereof having theusual characteristics ofthe rest of the chimney. Projecting laterally from two opposite verticalfaces of said section 3 are tubular connections 4, 4

adapted to receive the ends of the heating fines 5, 5. The saidconnections 4, 4 provide within themselves horizontal passages 6, 6opening within the section 3 into the central vertical passage 7 whichis a part of and preferably in alinement with the main passage 8 of thechimney 2. It will be understood that the said tubular connections at, 4project from the chimney into roomson opposite sides of the chimney, andthat there might be only one such connection, or more than two,according as the rooms are located. I have shown two in the drawing, forpurposes of illustration. Near the top of the room the chimney isprovided with a section 9 having lateral tubular connections 10,10similar to those of the section 3 already described, and in alinementtherewith. Aheat flue 5 is then middle and preferably upright bodyportion 12 and laterally bent and squared ends 13,13 one adapted totelescope onto the tubular connection 4 at the lower part of the roomand the other to similarly connect with the tubular connection 10 at thetop of the room. A branch or shunt flue is thus provided, lying whollywithin the room, through which the gaseous products of combustion can bedirected instead of through the chimney pro-per, ifdesired, as will nextbe described.

In order to direct and control the flow of gases from the lowerheat-flue section 3 into the heating fiue 5,1 provide in said sectiondampers or valves, one such damper 14 being adapted to close thevertical passage 7 of the section, and two other dampers 15, 15 beingarranged to open or close the horizontal passages 6, 6, when so desired.The damper 14 comprises a sheet or plate of metal 16 adapted to lie inclosed position upon a ledge 17 projecting fro-m the interior walls ofthe section passage, a hinge rod 18 being secured in fixed position tosaid sheet or plate near one edge thereof and preferably at its upperside, as shown, to swing the same. This rod 18 in the construction shownextends through the wall of the section 3, so as to project into bothrooms, and has at each end a laterally bent or projecting handle '19 bywhich said rod can be turned to swing the sheet or plate 16 into eitheropen or closed position, as will be understood, Obviously, in the caseof a single room, instead of rooms on opposite placed in each room,having a sides of the chimney, there would be only one projecting andhandled end of the hinge rod.

Each of the dampers 15 comprises a sheet or plate 20 of metal or othersuitable material, which is arranged transversely of the passage 6 andprovided near one edge of itself with a hinged rod 21 secured fiatwisethereto and projecting at one end through the tubular connection 4 toform a handle for turning, said handle 22 being preferably bentlaterally. A flange or web 23 projects from the inner side of thepassage 6 for the damper to close against, and although this flange orweb is shown inside the damper plate -20, it might obviously be placedon the outer side if preferred.

If no heat is desired in a room where one of the heat-fines is located,the damper 14 is tipped up into vertical position, or to i be moreexact-leaning against the side wall of the section passage so as toretain its pothrough the heat-flue 5 to warm the room.

The flue 5 is of course preferably made of sheet-metal or other materialadapted to readily transmit heat by conductivity to the surrounding end.

- The upper fiue section 9 has dampers 24:, 24in its tubular connections10, 10 and in its main upright passage 25 it has a damper 26 similar tothe one already described in connection with the lower heat-flue section8, except that this damper 26 lies in closed position across the passageof the section upon a ledge 27 beneath the tubular connections 10, 10.It will be understood that the dampers in the upper flue-section 9 areto be operated in a manner similar to those already described invconnection with the lower flue section 3, and simultaneously therewith.There is thus no chance for back draft or for flow of the gases in anydirection except straight up the chimney when the dampers are arrangedtherefor or around through the flue 5 when the dampers are arranged forthat.

By my lnvention adjacent to a chimney by utilizing the heat of the gasesand products of combustion passing upward therethrough and which heatwould otherwise be wasted.

- Having thus described'the invention, what I claim is- V 1. Thecombination with a chimney having upper and lowersections, eachproviding a lateral tubular connection, dampers in the main passagesofsaid sections, and dampers in the said tubular connections of aheat-flue extending betweensaid tubular connections outside the chimney.s v
